Amal Clooney hosted a party by husband George Clooney’s tequila company along with their business partner celeb couple Cindy Crawford and Randy Gerber who throws the annual Tequila Casamigos Halloween Party.

Each year, the event is attended by an A-list of celebrities.

The 1970s/Studio 54-themed event featured several other of our fave celeb mamas we’ve “bumpwatched” in the past including: Kim Kardashian-West with one of her BFFs Jonathan Cheban dresses as Sonny and Cher.

The event was held at the Old Tower Records spot in Los Angeles, California.

“[We] serve a lot of Casamigos and everyone just kind of lets loose and has a great time,” Gerber told Entertainment Tonight‘s Lauren Zima of how he pulls in the biggest crowd in Hollywood, year after year. “It’s really the one time everyone gets to let loose and play dress up, and pretty much everyone is friends. It’s all part of the House of Friends…. Everyone looks forward to that one night of the year.”
